BACKGROUND OF THE INVENTION Field of the Invention

The inventions herein relate to structures, such as dwellings and other buildings for residential occupancy, commercial occupancy and/or material storage, and to components for such structures.

Description of the Related Art

In the field of residential housing, the traditional technique for building homes is referred to as “stick-built” construction, where a builder constructs housing at the intended location using in substantial part raw materials such as wooden boards, plywood panels, and steel columns. The materials are assembled piece by piece over a previously prepared portion of ground, for example, a poured concrete slab or a poured concrete or cinder block foundation.

There have been a variety of efforts to depart from the conventional construction techniques used to create dwellings, as well as commercial spaces and like. One of the alternatives to stick-built construction is very generally referred to as modular housing. As opposed to stick-built construction, where the structure is built on-site, a modular house is constructed in a factory and then shipped to the site, often by means of a tractor-trailer.

Such modular housing often exceeds in size normally-permitted legal limits for road transport. For example, in the United States the maximum permitted dimensions for road transport are in general 102 inches (259.1 cm) in width, 13.5 feet (4.11 m) in height and 65 to 75 feet (19.81 to 22.86 m) in length. Thus, in many cases transporting a modular house from factory to site requires oversize load permits, which may impose restrictions on when transport can be undertaken and what routes can be utilized. Oversize road regulations may also require the use of an escort car and a trailing car as well. All of these requirements and restrictions inevitably increase the cost of the modular housing.

Significant advancements in the construction of dwellings and commercial space are described in U.S. Pat. Nos. 8,474,194, 8,733,029, 10,688,906, 10,829,029 and 10,926,689. In one aspect, these patents pertain to fabricating wall, floor and roof components in a factory that are folded together into a compact shipping module, and which are then transported to the intended location and unfolded to yield a fully formed structure.

SUMMARY OF THE INVENTION

The present inventions are directed to enclosure component sealing systems for foldable, transportable building structures. These foldable, transportable structures can include a number of wall, floor and roof components with exterior edges abutting top, bottom or interior faces of other wall, floor and roof components. In addition, these foldable, transportable structures can include a number of partitioned wall, floor and roof components with abutting interior edges when the enclosure components are fully unfolded.

The present inventions describe advancements in sealing the exterior edges and the abutting portions of the wall, floor and roof components to limit or prevent the ingress of rain water, noise and outside air into the interior of the structure. The present inventions include sealing systems that in general terms utilize two enclosure component sealing structures in pressing contact either when the building structure is manufactured, or later when the structure is transported to its final location and fully unfolded.

In one aspect, the present inventions are directed to an end cap, to be secured to an edge of a building structure enclosure component, which comprises a planar elongate seal plate having an interior face, an opposed exterior face, a first edge, an opposed second edge and a thickness. The interior face is adapted to be secured to the edge of the enclosure component, an elongate key is provided on the interior face of the seal plate, and an elongate accessory slot is defined in the exterior face of the seal plate, with the accessory slot having a depth less than the thickness of the seal plate. There is also provided a first locating slot extending from the first edge of the seal plate inwardly into the thickness of the seal plate toward the second edge, and a second locating slot extending from the second edge of the seal plate inwardly into the thickness of the seal plate toward the first edge.

In another aspect, the present inventions are directed to a perimeter seal assembly comprising an end cap and a perimeter board. The end cap comprises a planar elongate seal plate having a first interior face, an opposed first exterior face, a first edge and an opposed second edge, with the first interior face adapted to be secured to an edge of an enclosure component, an elongate seal key on the first interior face of the seal plate, and an elongate accessory slot defined in the first exterior face. The perimeter board comprises a planar elongate perimeter plate having a second interior face and an opposed second exterior face. The second interior face is positioned proximate to the first exterior face, with an elongate accessory key on the second interior face received in the accessory slot defined in the first exterior face. An elongate fastener slot is defined in the second exterior face, and an elongate clearance slot is defined in the second interior face of the perimeter plate, positioned between the accessory key and the first edge, or between the accessory key and the second edge.

In yet another aspect, the present inventions are directed to a roof seal assembly comprising an end cap and a roof skirt board. The end cap comprises a planar elongate seal plate having a first interior face and an opposed first exterior face, with the first interior face adapted to be secured to an edge of an enclosure component, an elongate seal key on the first interior face, and an elongate accessory slot defined in the first exterior face. The roof skirt board comprises a planar elongate skirt plate having a second interior face and an opposed second exterior face. The second interior face is positioned proximate to the first exterior face, with an elongate cinch key on the second interior face of the skirt plate received in the accessory slot defined in the first exterior face of the seal plate, and with the cinch key having a serpentine cross section. An elongate fastener slot is defined in the second exterior face of the skirt plate and is positioned proximate to the cinch key positioned on the second interior face.

These and other aspects of the present inventions are described in the drawings annexed hereto, and in the description of the preferred embodiments and claims set forth below.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

An embodiment of the foldable, transportable structure 150 in which the inventions disclosed herein can be implemented is depicted in FIGS. 1 through 5. When fully unfolded, as exemplified by FIG. 1, structure 150 has a rectangular shape made of three types of generally planar and rectangular enclosure components 155, the three types of enclosure components 155 consisting of a wall component 200, a floor component 300, and a roof component 400. As shown in FIGS. 1 and 2, the perimeter of structure 150 is defined by first longitudinal edge 106, first transverse edge 108, second longitudinal edge 116 and second transverse edge 110. For convenience, a direction parallel to first longitudinal edge 106 and second longitudinal edge 116 may be referred to as the “longitudinal” direction, a direction parallel to first transverse edge 108 and second transverse edge 110 may be referred to as the “transverse” direction; and a direction parallel to the vertical direction in FIG. 1 may be referred to as the “vertical” direction. Structure 150 as shown has one floor component 300, one roof component 400 and four wall components 200; although it should be understood that the present inventions are applicable to structures having other configurations as well.

Enclosure components 155 (wall component 200, floor component 300 and roof component 400) can be fabricated and dimensioned as described herein and positioned together to form a shipping module 100, shown end-on in FIG. 3. The enclosure components 155 are dimensioned so that the shipping module 100 is within U.S. federal highway dimensional restrictions. As a result, shipping module 100 can be transported over a limited access highway more easily, and with appropriate trailering equipment, transported without the need for oversize permits. Thus, the basic components of structure 150 can be manufactured in a factory, positioned together to form the shipping module 100, and the modules 100 can be transported to the desired site for the structure, where they can be readily assembled, as described herein.

Enclosure Component (155): General Description

The enclosure components 155 of the present invention include a number of shared design features that are described below.

A. Laminate Structure Design

Enclosure components 155 can be fabricated using a multi-layered, laminate design. A particular laminate design that can be used to fabricate enclosure components 155 comprises a first structural layer 210, a foam panel layer 213, a second structural layer 215 and a protective layer 218, as shown in FIG. 7 and described further below.

In particular, first structural layer 210 is provided in the embodiment of enclosure component 155 that is depicted in FIG. 7. First structural layer 210 in the embodiment shown comprises a sheet metal layer 205, which can be for example galvanized steel or aluminum. Sheet metal layer 205 is made from a plurality of generally planar rectangular metal sheets 206 positioned adjacent to each other to generally cover the full area of the intended enclosure component 155.

Referring again to FIG. 7, there is next provided in the depicted embodiment of enclosure component 155 a foam panel layer 213, comprising a plurality of generally planar rectangular foam panels 214 collectively presenting a first face 211 and a second opposing face 212. Foam panels 214 are made for example of expanded polystyrene (EPS) foam. A number of these foam panels 214 are positioned adjacent to each other and superposed first face-down on first structural layer 210 to generally cover the full area of the intended enclosure component 155. The foam panels 214 of foam panel layer 213 preferably are fastened to the metal sheets 206 of first structural layer 210 using a suitable adhesive, preferably a polyurethane based construction adhesive. Foam panel layer 213 can include exterior edge reinforcement and interior edge reinforcement, as described further below.

In the embodiment of the enclosure component 155 depicted in FIG. 7, there is next provided a second structural layer 215, having a first face that is positioned on the second opposing face 212 of foam panels 214 (the face distal from first structural layer 210), and also having a second opposing face. Second structural layer 215 in the embodiment shown comprises a sheet metal layer 216, which can be for example galvanized steel or aluminum. Sheet metal layer 216 is made from a plurality of generally planar rectangular metal sheets 217 positioned adjacent to each other and superposed first face-down on the second opposing face of foam panel layer 213 to generally cover the full area of the intended enclosure component 155. The metal sheets 217 of second structural layer 215 preferably are fastened to foam panel layer 213 using a suitable adhesive, preferably a polyurethane based construction adhesive.

In the embodiment of the enclosure component 155 depicted in FIG. 7, there is optionally next provided a protective layer 218, having a first face that is positioned on the second opposing face of second structural layer 215 (the face distal from foam panel layer 213), and also having a second opposing face. Optional protective layer 218 in the embodiment shown comprises a plurality of rectangular structural building panels 219 principally comprising an inorganic composition of relatively high strength, such as magnesium oxide (MgO). The structural building panels 219 are positioned adjacent to each other and superposed first face-down on the second opposing face of second structural layer 215 to generally cover the full area of the intended enclosure component 155. The building panels 219 of protective layer 218 preferably are fastened to second structural layer 215 using a suitable adhesive, preferably a polyurethane based construction adhesive. Protective layer 218 can be used if desired to impart a degree of fire resistance to the enclosure component 155, as well as to provide a pleasing texture and/or feel.

Other embodiments of multi-layered, laminate designs that can be used to fabricate the enclosure components 155 of the present invention, are described in U.S. Nonprovisional patent application Ser. No. 16/786,130, entitled “Foldable Building Structures with Utility Channels and Laminate Enclosures,” filed on Feb. 10, 2020, which has issued as U.S. Pat. No. 11,118,344. The contents of that U.S. Nonprovisional patent application Ser. No. 16/786,130, entitled “Foldable Building Structures with Utility Channels and Laminate Enclosures” and filed on Feb. 10, 2020 are incorporated by reference as if fully set forth herein, particularly including the multi-layered, laminate designs described for example at ¶¶0034-57 and depicted in FIGS. 4A-4D thereof.

B. Enclosure Component Exterior Edge Reinforcement

The exterior edges of each enclosure component 155 (i.e., the edges that define the perimeter of enclosure component 155) can be provided with exterior edge reinforcement, as desired. Exterior edge reinforcement generally comprises an elongate rigid member which can protect the foam panel material of foam panel layer 213 that would otherwise be exposed at the exterior edges of enclosure components 155. Exterior edge reinforcement can be fabricated from one or more of laminated strand lumber board, wooden board, C-channel extruded aluminum or steel, or the like, and is generally secured to the exterior edges of enclosure component 155 with fasteners, such as screw or nail fasteners, and/or adhesive.

C. Enclosure Component Partitioning

Enclosure components 155 in certain instances are partitioned into enclosure component portions to facilitate forming a compact shipping module 100. In those instances where an enclosure component 155 is partitioned into enclosure component portions, any exterior edge reinforcement on the exterior edges defining the perimeter of the enclosure component is segmented as necessary between or among the portions.

The enclosure component portions can be joined by hinge structures or mechanisms to permit the enclosure component portions to be “folded” and thereby contribute to forming a compact shipping module 100.

D. Enclosure Component Interior Edge Reinforcement

An enclosure component 155 partitioned into enclosure component portions will have interior edges. There will be two adjacent interior edges for each adjacent pair of enclosure component portions. Such interior edges can be provided with interior edge reinforcement. Similar to exterior edge reinforcement, such interior edge reinforcement generally comprises an elongate, rigid member which can protect the foam panel material of foam panel layer 213 which that would otherwise be exposed at the interior edges of enclosure components 155. Interior edge reinforcement can be fabricated from one or more of laminated strand lumber board, wooden board, C-channel extruded aluminum or steel, or the like, and is generally secured to the interior edges of enclosure component 155 with fasteners, such as screw or nail fasteners, and/or adhesive.

E. Enclosure Component Load Transfer

In the case of enclosure components 155, it is necessary to transfer the loads imposed on their surfaces to their exterior edges, where those loads can be transferred either to or through adjoining walls, or to the building foundation. For enclosure components 155 that are horizontally oriented when in use (floor component 300 and roof component 400), such loads include the weight of equipment, furniture and people borne by their surfaces, as well as vertical seismic loads. For enclosure components that are vertically oriented when in use (wall component 200), such loads include those arising from meteorological conditions (hurricanes, tornadoes, etc.) and human action (vehicle and other object impacts).

For this purpose, multi-layered, laminate designs as shown in FIG. 7 will function to transfer the loads described above. To add additional load transfer capability, structural members, such as beams and/or joists, can be utilized within the perimeter of the enclosure components 155, as is deemed appropriate to the specific design of structure 150 and the particular enclosure component 155, to assist in the transfer of loads to the exterior edges. Particular embodiments of such structural members, which also incorporate hinge structures, are described in U.S. Provisional Patent Application No. 63/188,101, filed May 13, 2021, entitled “Folding Beam Systems” and having the same inventors as this disclosure.

Further design details of wall component 200, floor component 300, and roof component 400 are provided in the sections following.

Wall Component (200)

Typically, a structure 150 will utilize four wall components 200, with each wall component 200 corresponding to an entire wall of structure 150.

A. General Description

Wall component 200 has a generally rectangular perimeter. As shown in FIG. 1, wall components 200 have plural apertures, specifically a door aperture 202, which has a door frame and door assembly, and plural window apertures 204, each of which has a window frame and a window assembly. The height and length of wall components 200 can vary in accordance with design preference, subject as desired to the dimensional restrictions applicable to transport, described above. In this disclosure, structure 150 is fashioned with all sides of equal length; accordingly, its first and second longitudinal edges 106 and 116, and its first and second transverse edges 108 and 110, are all of equal length. It should be understood however, that the inventions described herein are applicable to structures having other dimensions, such as where two opposing wall components 200 are longer than the other two opposing wall components 200.

As indicated above, wall components 200 of the present inventions can utilize a multi-layered, laminate design. In the embodiment depicted in FIGS. 1 through 6, wall component 200 utilizes the multi-layered, laminate design shown in FIG. 7 employing these particular elements: sheet metal layer 205 of first structural layer 210 is 24 gauge galvanized steel approximately 0.022-0.028 inch thick, the foam panels 214 of foam panel layer 213 are EPS foam approximately 5.68 inches thick, the sheet metal layer 216 of second structural layer 215 is 24 gauge galvanized steel approximately 0.022-0.028 inch thick, and the building panels 219 of protective layer 218 are MgO board approximately 0.25 inch (6 mm) thick.

The perimeter of each wall component 200 is generally provided with exterior edge reinforcement. As exemplified by wall component 200 shown in FIG. 6, the exterior edge reinforcement for wall component 200 is a floor plate 220 along the bottom horizontal edge, a ceiling plate 240 along the top horizontal edge and two end pieces 270 respectively fastened at each vertical edge of wall component 200. In the case of a wall component 200, exterior edge reinforcement provides regions for fastening like regions of abutting wall components 200, roof component 400 and floor component 300, in addition to protecting the exterior edges of foam panel material.

In the embodiment shown in FIGS. 1 through 6, the exterior edge reinforcement for wall component 200 provided by floor plate 220, ceiling plate 240, and end pieces 270 is fabricated from laminated strand lumber board 5.625″ deep and 1.5″ thick.

B. Partitioned Wall Components

Referring to FIG. 2, structure 150 has two opposing wall components 200, where one of the two opposing wall components 200 comprises first wall portion 200 s-1 and second wall portion 200 s-2, and the other of the two opposing wall components 200 comprises third wall portion 200 s-3 and fourth wall portion 200 s-4. Each of wall portions 200 s-1, 200 s-2, 200 s-3 and 200 s-4 has a generally rectangular planar structure. As shown in FIG. 2, the interior vertical edge 192-1 of wall portion 200 s-1 is proximate to a respective interior vertical edge 192-2 of wall portion 200 s-2, and the interior vertical edge 194-3 of wall portion 200 s-3 is proximate a respective interior vertical wall edge 194-4 of wall portion 200 s-4. Interior edge reinforcement can be provided at any one or more of vertical edges 192-1, 192-2, 194-3 and 194-4. In the embodiment shown in FIGS. 1 through 6, the interior edge reinforcement provided at vertical edges 192-1, 192-2, 194-3 and 194-4 is fabricated from laminated strand lumber board 5.625″ deep and 1.5″ thick.

Referring again to FIG. 2, first wall portion 200 s-1 is fixed in position on floor portion 300 a proximate to first transverse edge 108, and third wall portion 200 s-3 is fixed in position on floor portion 300 a, opposite first wall portion 200 s-1 and proximate to second transverse edge 110. First wall portion 200 s-1 is joined to second wall portion 200 s-2 with a hinge structure that permits wall portion 200 s-2 to pivot about vertical axis 192 between a folded position and an unfolded position, and third wall portion 200 s-3 is joined to fourth wall portion 200 s-4 with a hinge structure to permit fourth wall portion 200 s-4 to pivot about vertical axis 194 between a folded position and an unfolded position.

Notably, first wall portion 200 s-1 is longer than third wall portion 200 s-3 by a distance approximately equal to the thickness of wall component 200, and second wall portion 200 s-2 is shorter than third wall portion 200 s-3 by a distance approximately equal to the thickness of wall component 200. Furthermore, wall portion 200 s-1 and wall portion 200 s-3 are each shorter in length (the dimension in the transverse direction) than the dimension of floor portion 300 a in the transverse direction. Dimensioning the lengths of wall portions 200 s-1, 200 s-2, 200 s-3 and 200 s-4 in this manner permits wall portions 200 s-2 and 200 s-4 to nest against each other in an overlapping relationship when in an inwardly folded position. In this regard, FIG. 2 depicts wall portions 200 s-2 and 200 s-4 both in their unfolded positions, where they are labelled 200 s-2 u and 200 s 4-u respectively, and FIG. 2 also depicts wall portions 200 s-2 and 200 s-4 both in their inwardly folded positions, where they are labelled 200 s-2 f and 200 s 4-f respectively. When wall portions 200 s-2 and 200 s-4 are in their inwardly folded positions (200 s-2 f and 200 s-4 f), they facilitate forming a compact shipping module. When wall portion 200 s-2 is in its unfolded position (200 s-2 u), it forms with wall portion 200 s-1 a wall component 200 proximate first transverse edge 108, and when wall portion 200 s-4 is in its unfolded position (200 s-4 u), it forms with wall portion 200 s-3 a wall component 200 proximate second transverse edge 110.

The hinge structures referenced above, for securing first wall portion 200 s-1 to second wall portion 200 s-2, and third wall portion 200 s-3 to fourth wall portion 200 s-4, can be surface mounted or recessed, and of a temporary or permanent nature. The provision of interior edge reinforcement, as described above, can provide a region for securing such hinge structures. Suitable hinge structures can be fabricated for example of ferrous or non-ferrous metal, plastic or leather material.

C. Unpartitioned Wall Components

As compared to the two wall components 200 proximate first and second transverse edges 108 and 110, which are partitioned into wall portions, the remaining two wall components 200 proximate first and second longitudinal edges 106 and 116 do not comprise plural wall portions, but rather each is a single piece structure. However, one of these wall components 200, which is sometimes denominated 200P in this disclosure, and which is located on floor portion 300 b proximate first longitudinal edge 106, is pivotally secured to floor portion 300 b by means of hinge structures to permit wall component 200P to pivot about horizontal axis 105 shown in FIG. 3 from a folded position to an unfolded position. Pivotally securing wall component 200P also facilitates forming a compact shipping module 100. The remaining wall component 200, sometimes denominated 200R in this disclosure, is rigidly secured on floor portion 300 a proximate second longitudinal edge 116 and abutting the vertical edges of first wall portion 200 s-1 and third wall portion 200 s-3 proximate to second longitudinal edge 116, as shown in FIG. 2.

The hinge structures referenced above, for securing wall component 200P to floor portion 300 b, can be surface mounted or recessed, and of a temporary or permanent nature. The provision of exterior edge reinforcement, as described above, can provide a region for securing such hinge structures. Suitable hinge structures can be fabricated for example of ferrous or non-ferrous metal, plastic or leather material.

Floor Component (300)

Typically, structure 150 will utilize one floor component 300; thus floor component 300 generally is the full floor of structure 150.

A. General Description

Floor component 300 has a generally rectangular perimeter. FIGS. 4 and 5 depict floor component 300 in accordance with the present inventions. The perimeter of floor component 300 is defined by first longitudinal floor edge 117, first transverse floor edge 120, second longitudinal floor edge 119 and second transverse floor edge 118. In particular, (a) first longitudinal floor edge 117, (b) first transverse floor edge 120, (c) second longitudinal floor edge 119 and (d) second transverse floor edge 118 generally coincide with (i.e., underlie) (w) first longitudinal edge 106, (x) first transverse edge 108, (y) second longitudinal edge 116 and (z) second transverse edge 110, respectively, of structure 150.

The length and width of floor component 300 can vary in accordance with design preference. In the particular embodiment of structure 150 depicted in FIGS. 2, 4 and 5, floor component 300 is approximately 19 feet (5.79 m) by 19 feet (5.79 m).

Floor component 300 and its constituent elements are generally designed and dimensioned in thickness and in other respects to accommodate the particular loads to which floor component 300 may be subject. It is preferred that floor component 300 utilize a multi-layered, laminate design, such as that described in connection with FIG. 7. In the embodiment shown in FIGS. 4 and 5, the bottom-most surface of floor component 300 comprises sheet metal layer 205 of first structural layer 210, with sheet metal layer 205 being 24 gauge galvanized steel approximately 0.022-0.028 inch thick. Above sheet metal layer 205 there are provided foam panels 214 of foam panel layer 213. In the embodiment shown in FIGS. 4 and 5, foam panels 214 are EPS foam approximately 7.125 inches thick. Above foam panel layer 213 there is provided sheet metal layer 216 of second structural layer 215, with sheet metal layer 216 being 24 gauge galvanized steel approximately 0.022-0.028 inch thick. Above sheet metal layer 216 of second structural layer 215, there are provided building panels 219 of protective layer 218, with building panels 219 being MgO board approximately 0.25 inch (6 mm) thick.

The perimeter of each floor component 300 is generally provided with exterior edge reinforcement.

Reinforcing boards 307 can be made of laminated strand lumber board 7.125″ deep and 1.5″ thick.

Roof Component (400)

Typically, structure 150 will utilize one roof component 400; thus roof component 400 generally is the full roof of structure 150.

A. General Description

Roof component 400 has a generally rectangular perimeter. FIGS. 1, 4 and 5 depict roof component 400 in accordance with the present inventions. The perimeter of roof component 400 is defined by first longitudinal roof edge 406, first transverse roof edge 408, second longitudinal roof edge 416 and second transverse roof edge 410. In particular, (a) first longitudinal roof edge 406, (b) first transverse roof edge 408, (c) second longitudinal roof edge 416 and (d) second transverse roof edge 410 of roof component 400 generally coincide with (i.e., overlie) (w) first longitudinal edge 106, (x) first transverse edge 108, (y) second longitudinal edge 116 and (z) second transverse edge 110, respectively, of structure 150.

The length and width of roof component 400 can vary in accordance with design preference. In the particular embodiment of structure 150 depicted in FIGS. 1, 4 and 5, the length and width of roof component 400 approximates the length and width of floor component 300.

Roof component 400 and its constituent elements are generally designed and dimensioned in thickness and in other respects to accommodate the particular loads to which roof component 400 may be subject. It is preferred that roof component 400 utilize a multi-layered, laminate design, such as that described in connection with FIG. 7. In the embodiment shown in FIGS. 4 and 5, the top-most surface of roof component 400 comprises sheet metal layer 205 of first structural layer 210, with sheet metal layer 205 being 24 gauge galvanized steel approximately 0.022-0.028 inch thick. Below sheet metal layer 205 there are provided foam panels 214 of foam panel layer 213, with foam panels 214 in the embodiment shown in FIGS. 4 and 5 being EPS foam for example approximately 7.125 inches thick. Below foam panel layer 213 there is provided sheet metal layer 216 of second structural layer 215, with sheet metal layer 216 being 24 gauge galvanized steel approximately 0.022-0.028 inch thick. Below sheet metal layer 216 of second structural layer 215, there are provided building panels 219 of protective layer 218, with building panels 219 being MgO board approximately 0.25 inch (6 mm) thick.

The perimeter of roof component 400 is generally provided with exterior edge reinforcement. As exterior edge reinforcement for the embodiment of roof component 400 shown in FIGS. 4 and 5, a first shoulder beam 435 (visible edge-on in FIG. 4) is positioned at the first longitudinal roof edge 406 of roof component 400, a second shoulder beam 435 (visible edge-on in FIG. 5) is positioned at the first transverse roof edge 408 of roof component 400, a third shoulder beam 435 (visible edge-on in FIG. 5) is positioned at the second transverse roof edge 410 of roof component 400, and a fourth shoulder beam 435 (visible edge-on in FIG. 4) is positioned at the second longitudinal roof edge 416 of roof component 400. In addition to protecting the exterior edges of foam panel material, the exterior edge reinforcement provided by shoulder beams 435 assists in resisting vertical loads and transferring such loads to lower floors through underlying wall components 200 supporting roof component 400, and then to the foundation of the structure 150. Such exterior edge reinforcement can also provide a region for fastening like regions of abutting enclosure components 155 (underlying and any overlying). Shoulder beams 435 of roof component 400 can be fabricated from laminated strand lumber board 7.125″ deep and 1.5″ thick.

B. Roof Partitioning

The roof component 400 of structure 150 is partitioned into roof portions 400 a, 400 b and 400 c. FIG. 1 shows roof portions 400 a, 400 b and 400 c in perspective view, and FIG. 4 shows roof portions 400 a, 400 b and 400 c in section view, edge-on.

Each of the roof portions 400 a, 400 b and 400 c is a planar generally rectangular structure, with roof portion 400 a adjoining roof portion 400 b, and roof portion 400 b adjoining roof portion 400 c. Interior edge 412 c of roof component 400 c abuts a first interior edge 412 b of roof component 400 b, as shown in FIG. 4. For interior edge reinforcement, a reinforcing board 437 is positioned adjacent interior edge 412 c, and a reinforcing board 437 is positioned against first interior edge 412 b. Interior edge 412 a of roof portion 400 a abuts a second interior edge 412 b of roof portion 400 b, as shown in FIG. 4. For interior edge reinforcement, a reinforcing board 437 is positioned adjacent interior edge 412 a, and a reinforcing board 437 is positioned against second interior edge 412 b. Additional structural members, such as beams and/or joists, can be utilized within the perimeter of one or more of roof portions 400 a, 400 b and 400 c, as is deemed appropriate to the specific design of structure 150 and roof component 400, to assist in the transfer of vertical loads to one or more shoulder beams 435.

Referring to structure 150 shown in FIG. 4, roof portion 400 a is fixed in position relative to first wall portion 200 s-1, third wall portion 200 s-3 and wall component 200R. Roof portion 400 a is joined to roof portion 400 b with hinge structures provided between interior edge 412 a of roof portion 400 a and second interior edge 412 b of roof portion 400 b. Such hinge structures are adapted to permit roof portion 400 b to pivot through up to one hundred and eighty degrees (180°) of arc about a horizontal axis 405 a, located proximate the top of roof component 400 and shown in FIG. 4, between the fully folded position shown in FIG. 3, where roof portion 400 b lies flat against roof portion 400 a, and the fully unfolded position shown in FIG. 4.

In turn, roof portion 400 b is joined to roof portion 400 c with hinge structures provided between first interior edge 412 b of roof portion 400 b and interior edge 412 c of roof portion 400 c. Such hinge structures are adapted to permit roof portion 400 c to pivot through up to one hundred and eighty degrees (180°) of arc about a horizontal axis 405 b, located proximate the bottom of roof component 400 and shown in FIG. 4, between the folded position shown in FIG. 3, where roof portion 400 c lies flat against roof portion 400 b (when roof portion 400 b is positioned to lie flat against roof portion 400 a), and the fully unfolded position shown in FIG. 4.

The hinge structures joining roof portions 400 a, 400 b and 400 c can be surface mounted or recessed, and of a temporary or permanent nature. Suitable hinge structures can be fabricated for example of ferrous or non-ferrous metal, plastic or leather material. The interior edge reinforcement provided by reinforcing boards 437 of roof portions 400 a, 400 b and 400 c can provide a region for mounting hinge structures, in addition to protecting the edges of foam panel material. Reinforcing boards 437 can be fabricated from laminated strand lumber board 7.125″ deep and 1.5″ thick.

Enclosure Component Sealing Systems

Structure 150 can utilize the enclosure component sealing systems described below to limit or prevent the ingress of rain water, noise and outside air into the interior of structure 150.

A. General Description

The enclosure component sealing systems for structure 150 utilize the sealing structures described below. Except for I-beam end cap 221, which functions to seal the edges of select enclosure components 155, the enclosure component sealing systems comprise in general terms two enclosure component sealing structures, paired in in pressing contact in different combinations, to seal the junctions between different regions of the enclosure components 155 found in structure 150. These junctions consist of either two interior edges of adjacent enclosure component portions, positioned edge-to-edge when structure 150 is unfolded, or an exterior edge of an enclosure component 155 which abuts an interior surface of another enclosure component 155. Where an enclosure component sealing structure is positioned on an interior or exterior edge of an enclosure component 155, there can respectively be provided interior edge reinforcement or exterior edge reinforcement between the sealing structure and the respective interior or exterior edge of the foam panel layer 213 in the case where the multi-layered, laminate design depicted in FIG. 7 is utilized (such that the enclosure component sealing structure is positioned proximate to the interior or exterior edge, as the case may be, of the foam panel layer 213).

The specific enclosure component sealing structures described below are I-beam end cap 221; wall vertical interlock 245; wall end cap 246; I-beam interlock A 250; I-beam interlock B 251; floor top plate 252; roof bottom plate 255; floor top interlock 261; wall end interlock A 262; and wall end interlock B 263. Excepting I-beam end cap 221, each of the foregoing enclosure component sealing structures utilizes either two or more compression seals 230, or one shear seal 260, which are also described below. Exemplary placements of the enclosure component sealing structures described herein are found in Subsections B. through J. below and also in the Section below entitled “Enclosure Component Sealing Structure Exemplary Placements”.

The current inventions include two closure boards, namely perimeter board 310 and roof skirt board 280. These closure boards, which are described below, are utilized in conjunction with I-beam end cap 221 to provide additional sealing, as well as to realize additional benefits.

B. I-Beam End Cap (221)

I-beam end cap 221, shown in cross-section in FIG. 10, is a rigid elongate member that is fastened to the periphery of select enclosure components 155, preferably the exterior edges of floor component 300 and roof component 400. I-beam end cap 221 constitutes an edge seal that performs a sealing function against water ingress into and environmental exposure of the edge of the enclosure component 155 to which it is secured, and imparts impact resistance to that edge.

FIG. 10 shows an exemplary installation of I-beam end cap 221 secured to the edge of a schematic representation of floor portion 300 a. In particular, I-beam end cap 221 has an elongate seal plate 223 with seal plate 223 having an elongate interior face 226 and an opposing elongate planar exterior face 227. I-beam end cap 221 has a length and width the same, or substantially the same, as the length and width of the exterior edge of floor portion 300 a, so as to cover the entirety, or substantially the entirety, of the exterior edge of floor portion 300 a.

At the mid-point of the interior face 226 of seal plate 223, there is provided an elongate key 222, which is rectangular in cross section (as shown in FIG. 10), and has a length the same, or substantially the same, as the length of I-beam end cap 221. Key 222 is received in a corresponding slot formed in the exterior edge reinforcement positioned on the exterior edge of the enclosure component 155 to which I-beam end cap 221 is secured. Thus for example, FIG. 9 depicts key 222 of an I-beam end cap 221 received in slot 422 of a shoulder beam 435 of roof portion 400 a. Each of the top and bottom edges of I-beam end cap 221 define locating slots 229. In the case where the enclosure component 155 utilizes the enclosure component laminate design shown in FIG. 7, locating slots 229 receive the edge portions 207 of metal sheets 206 and 217 (of sheet metal layers 205 and 216 respectively), bent down at a ninety degree (90°) angle, as shown in FIG. 9.

Still referring to FIG. 10, the exterior face 227 of seal plate 223 of I-beam end cap 221 includes an elongate accessory slot 224, which is rectangular in cross section and has a length the same, or substantially the same, as the length of the exterior face 227 of I-beam end cap 221. The exterior face 227 further includes a plurality of elongate fastener locating grooves 225, each of which has a length the same, or substantially the same, as the length of seal plate 223. I-beam end cap 221 can be secured to an exterior edge of an enclosure component 155, such as the roof portion 400 a shown in FIG. 9 and the floor portion 300 a shown in FIG. 10, for example by adhesive applied to interior face 226, or by fasteners, such as screw or nail fasteners, spaced apart along the length of I-beam end cap 221 and driven through the exterior face 227, or by utilizing a combination of adhesive and fasteners. Locating grooves 225 assist in accurate positioning of such fasteners.

C. Compression Seal (230)

A number of the enclosure component sealing systems described herein and utilized in structure 150 include a compression seal system. An element of that compression seal system is a compression seal 230.

Compression seal 230, which is shown in cross-section in FIG. 11A, is an elongate member having in cross-section an elongate base 231 with an elongate arched portion 232 that is flanked by two elongate winglets 233. At the intersection of the arched portion 232 of base 231 and each of the winglets 233, there are provided two opposed elongate seal walls 234, joined to and extending away from base 231 in a diverging relationship at a divergence angle θ, where θ<180°, for example θ<90° or in the range of 40°<θ<50°. It is most preferred that θ be the same, or nearly so, as the divergence angle of the slot walls 244 described below. Thus as shown in FIG. 11A, the ends of the seal walls 234 distal from base 231 are further apart than the ends of the seal walls proximate to base 231.

At the ends of the seal walls 234 distal from base 231, each seal wall 234 is joined to an elongate arcuate buttress 235. The end of each arcuate buttress 235, distal from the seal wall 234 to which it is joined, is in turn joined to a respective planar elongate seal surface 236; thus there are two planar seal surfaces 236 in compression seal 230. The planar seal surfaces 236 extend away from the seal walls 234 in a converging relationship at a convergence angle δ, where δ<180°, for example 90°. Thus the ends of seal surfaces 236 distal from arcuate buttresses 235 are closer together than the ends of seal surfaces 236 proximate to arcuate buttresses 235. The ends of seal surfaces 236 distal from arcuate buttresses 235 are joined by an elongate seal closure 237. The base 231, seal walls 234, arcuate buttresses 235, seal surfaces 236 and seal closure 237 thereby define a hollow elongate seal chamber 238, as shown in FIG. 11A. Seal closure 237 is curved in shape toward seal chamber 238, such as to assume a cupped appearance.

Seal 230 is intended to be received in an elongate seal slot 240, shown for example in FIG. 11B. Slot 240 in general has a dovetail shape, with an elongate planar floor 241 flanked by two elongate lateral grooves 242, and with an elongate planar slot wall 244 abutting and extending from each groove 242 toward an elongate shoulder 243 at the surface of the slot 240. Thus there are two opposed shoulders 243 in seal slot 240. The planar slot walls 244 extend away from grooves 242 in a diverging relationship at a divergence angle ε, where ε<180° (for example ε<90° or in the range of 40°<ε<50°), such that the edges of slot walls 244 coincident with shoulders 243 are further apart than the edges of slot walls 244 abutting grooves 242. Compression seal 230 is dimensioned to snugly fit within slot 240, as shown in FIG. 11B, such that winglets 233 are received in grooves 242 and the arched portion 232 of base 231 is compressed sufficiently to provide a resilient force that urges winglets 233 into grooves 242 and causes seal 230 to be retained in its proper position in slot 240 during fabrication and following fabrication of the enclosure component 155.

When two enclosure components 155 on which are mounted two paired enclosure component sealing structures, one of which bears a compression seal 230, are appropriately positioned and pressed together, compression seal 230 will be squeezed against the planar exterior face 227 of the opposed seal plate 223, which causes seal closure 237 and arcuate buttresses 235 to be urged into seal chamber 238. This permits the two planar exterior faces 227 of the pressed-together seal plates 223 of the paired sealing structures to come into full contact. At the same time, arcuate buttresses 235 rotate down and seal surfaces 236 are urged into a generally coplanar relationship (with arcuate buttresses 238 functioning as hinges) with the opposing planar exterior face 227 pressing against it, to create two lines of sealing.

Compression seal 230 can be fabricated from a resilient material, such as rubber or plastic, for example polyurethane. Particular embodiments of enclosure component sealing structures utilizing the foregoing compression sealing system are described below.

D. Wall Vertical Interlock (245), Wall End Cap (246) Sealing System

FIG. 12 depicts in exploded form the junction between a wall vertical interlock 245 and a wall end cap 246. The particular junction is shown for illustrative purposes between wall portion 200 s-1 and 200 s-2, with wall vertical interlock 245 positioned on the interior vertical edge of wall portion 200 s-2 (interior vertical edge 192-2 shown in FIG. 2) and wall end cap 246 positioned on the interior vertical edge of wall portion 200 s-1 (interior vertical edge 192-1 shown in FIG. 2). In structure 150, wall vertical interlock 245 and wall end cap 246 shown in FIG. 12 are vertically-oriented.

In particular, wall vertical interlock 245 is a rigid elongate member that has an elongate seal plate 223 with an elongate interior face 226 and an opposing elongate planar exterior face 227. The exterior face 227 preferably is hard and smooth to provide a good sealing surface. Seal plate 223 has a length and width the same, or substantially the same, as the length and width of the interior edge of wall portion 200 s-2, so as to cover the entirety, or substantially the entirety, of that interior edge of wall portion 200 s-2.

As shown in FIG. 12, at the mid-point of the interior face 226 of wall vertical interlock 245 there is provided an elongate key 222, which is rectangular in cross section has a length the same, or substantially the same, as the length of seal plate 223. Key 222 is received in a corresponding elongate slot formed in the interior edge reinforcement positioned on the interior vertical edge of wall portion 200 s-2, to which wall vertical interlock 245 is secured. Each of the top and bottom edges of wall vertical interlock 245 define elongate locating slots 229 for receiving the edge portions of sheet metal layers 205 and 216, when bent down at a ninety degree (90°) angle. In addition, the edge of one of the slots 229 abutting the interior face 226 of wall vertical interlock 245 is terminated an inset distance “I” from the opposing edge of that slot, where I is the thickness of the protective layer 218, such as magnesium oxide (MgO) board.

Still referring to FIG. 12, at the mid-point of the exterior face 227 of seal plate 223 of wall vertical interlock 245 there is provided an elongate interlock slot 228, which is rectangular in cross-section and has a length the same, or substantially the same, as the length of the exterior face 227 of wall vertical interlock 245. Two elongate seal slots 240 are defined on the exterior face 227 of wall vertical interlock 245, one above interlock slot 228 and the other below interlock slot 228, as shown in FIG. 12. Each slot 240 has a length the same, or substantially the same, as the length of wall vertical interlock 245.

Wall vertical interlock 245 can be secured to the vertical edge of wall portion 200 s-2 shown in FIG. 12 for example by adhesive applied to interior face 226, or by fasteners, such as screw or nail fasteners, spaced apart along the length of wall vertical interlock 245 and driven through the exterior face 227, or by utilizing a combination of adhesive and fasteners.

FIG. 12 additionally depicts a wall end cap 246. Wall end cap 246 shown in FIG. 12 is a rigid elongate member that is defined by an elongate seal plate 223 having an elongate interior face 226 and an opposing elongate planar exterior face 227. The exterior face 227 preferably is hard and smooth to provide a good sealing surface. Seal plate 223 has a length and width the same, or substantially the same, as the length and width of the exterior edge of wall portion 200 s-1, so as to cover the entirety, or substantially the entirety, of the vertical edge of wall portion 200 s-1 shown in in FIG. 12.

At the mid-point of the interior face 226 of wall end cap 246 show in in FIG. 12 there is provided an elongate key 222, which is rectangular in cross-section and has a length the same, or substantially the same, as the length of seal plate 223. Key 222 of wall end cap 246 is received in a corresponding elongate slot formed in the interior edge reinforcement, positioned on the interior vertical edge of wall portion 200 s-1, to which wall end cap 246 is secured. Each of the top and bottom edges of wall end cap 246 define elongate locating slots 229 for receiving the edge portions of sheet metal layers 205 and 216, when bent down at a ninety degree (90°) angle. In addition, the edge of one of the slots 229 abutting the interior face 226 of wall end cap 246 is terminated an inset distance “I” from the opposing edge of that slot, where I is the thickness of the protective layer 218, such as magnesium oxide (MgO) board.

Wall end cap 246 can be secured to the vertical edge of wall portion 200 s-1 shown in FIG. 12 for example by adhesive applied to interior face 226, or by fasteners, such as screw or nail fasteners, spaced apart along the length of wall end cap 246 and driven through the exterior face 227, or by utilizing a combination of adhesive and fasteners.

In FIG. 12, wall vertical interlock 245 mates with wall end cap 246. For this purpose, at the mid-point of the exterior face 227 of seal plate 223 of wall end cap 246 there is provided an elongate interlock key 247, which is rectangular in cross-section and has a length the same, or substantially the same, as the length of the exterior face 227 of wall end cap 246. Interlock key 247 mates with interlock slot 228 when wall vertical interlock 245 and wall end cap 246 are pressed together. Additionally, the two edges of wall end cap 246 are provided with elongate coupling ridges 248 which mate with elongate coupling insets 249 located at the edges of wall vertical interlock 245. Coupling ridges 248 and coupling insets 249 can have the same, or approximately the same, lengths as wall end cap 246 and wall vertical interlock 245 respectively.

Prior to mating wall vertical interlock 245 with wall end cap 246, a compression seal 230 is placed in each of the two seal slots 240 of wall vertical interlock 245, with each seal 230 having the same, or approximately the same, length as the slot 240 in which it is inserted. When wall vertical interlock 245 with wall end cap 246 are pressed together in a mating relationship, the two compression seals 230 are deformed in the manner described previously to provide four lines of sealing between wall vertical interlock 245 and wall end cap 246.

E. I-Beam Interlock A (250), I-Beam Interlock B (251) Sealing System

FIG. 14 depicts in exploded form the junction between an I-beam interlock A 250 and an I-beam interlock B 251, each shown in cross-section. The particular junction is shown for illustrative purposes between roof portion 400 b and roof portion 400 c, with I-beam interlock A 250 positioned on the interior edge 412 c of roof portion 400 c, and with I-beam interlock B 251 positioned on first interior edge 412 b of roof portion 400 b. In structure 150, I-beam interlock A 250 and I-beam interlock B 251 shown in FIG. 14 are horizontally-oriented.

In particular, I-beam interlock A 250 is a rigid elongate member that is defined by an elongate seal plate 223 having an elongate interior face 226 and an opposing elongate planar exterior face 227. The exterior face 227 preferably is hard and smooth to provide a good sealing surface. Seal plate 223 has a length and width the same, or substantially the same, as the length and width of the interior edge 412 c of roof portion 400 c shown in FIG. 14, so as to cover the entirety, or substantially the entirety, of that interior edge.

As shown in FIG. 14, at the mid-point of the interior face 226 of I-beam interlock A 250 there is provided an elongate key 222, which has a rectangular cross-section and a length the same, or substantially the same, as the length of I-beam interlock A 250. Key 222 is received in a corresponding elongate slot formed in the interior edge reinforcement positioned on the horizontal edge of roof portion 400 c, to which I-beam interlock A 250 is secured. Each of the top and bottom edges of I-beam interlock A 250 define elongate locating slots 229 for receiving the edge portions of sheet metal layers 205 and 216, bent down at a ninety degree (90°) angle. In addition, the edge of one of the slots 229 abutting the interior face 226 of I-beam interlock A 250 is terminated an inset distance “I” from the opposing edge of that slot, where I is the thickness of the protective layer 218, such as magnesium oxide (MgO) board.

In FIG. 14, I-beam interlock A 250 mates with I-beam interlock B 251. For this purpose, in the lower half of the exterior face 227 of seal plate 223 of I-beam interlock B 251 there is provided an elongate interlock key 247, which has a rectangular cross-section and a length the same, or substantially the same, as the length of I-beam interlock B 251.

Floor top plate 252 can be secured to the top edge of floor portion 300 a proximate to second longitudinal floor edge 119 shown in FIG. 15 for example by adhesive applied to interior face 226, or by fasteners, such as screw or nail fasteners, spaced apart along the length of floor top plate 252 and driven through the exterior face 227, or by utilizing a combination of adhesive and fasteners.

FIG. 15 additionally depicts a wall end cap 246 positioned along the bottom edge of wall component 200R. The design of wall end cap 246 was previously described in connection with FIG. 12. The seal plate 223 of wall end cap 246 shown in FIG. 15 has a length and width the same, or substantially the same, as the length and width of the bottom edge of wall component 200R, so as to cover the entirety, or substantially the entirety, of the bottom edge of wall component 200R shown in in FIG. 15.

G. Roof Bottom Plate (255), Wall End Cap (246) Sealing System

FIG. 13 depicts in exploded form the junction between a roof bottom plate 255 and a wall end cap 246, each shown in cross-section. The particular junction shown for illustrative purposes is between wall component 200R and roof portion 400 a, with roof bottom plate 255 positioned along the lower face of roof portion 400 a adjacent second longitudinal roof edge 416, and wall end cap 246 positioned on the top edge of wall component 200R. In structure 150, wall component 200R in FIG. 13 is vertically oriented and roof portion 400 a is horizontally oriented.

The design of roof bottom plate 255 shown in FIG. 13 is substantially the same as floor top plate 252 shown in FIG. 15, except that roof bottom plate 255 is thinner because it need not accommodate the thickness of any flooring; for example, roof bottom plate 255 can have a thickness “I”, equal to the thickness of an abutting protective layer 218, such as MgO board. Roof bottom plate 255 in FIG. 13 is a rigid elongate member that has an elongate seal plate 223 with an elongate planar interior face 226 and an opposing elongate planar exterior face 227. The exterior face 227 preferably is hard and smooth to provide a good sealing surface.

As shown in FIG. 13, at the exterior edge of the interior face 226 of roof bottom plate 255, proximate to second longitudinal roof edge 416, there is provided a series of elongate stepped locating ridges 254. These stepped locating ridges, which have a length the same, or substantially the same, as the length of roof bottom plate 255, mesh with the corresponding stepped locating ridges 253 of wall end cap 221 depicted in FIG. 10 and with dashed lines in FIG. 13, and positioned at the exterior edge of roof portion 400 a.

Still referring to FIG. 13, at the mid-point of the exterior face 227 of seal plate 223 of roof bottom plate 255 there is provided an elongate interlock slot 228, which has a rectangular cross-section and a length the same, or substantially the same, as the length of roof bottom plate 255. There are two elongate seal slots 240 defined on the exterior face 227 of roof bottom plate 255, one on each side of interlock slot 228, as shown in FIG. 13. Each seal slot 240 has a length the same, or substantially the same, as the length of roof bottom plate 255.

Roof bottom plate 255 can be secured to the bottom face of roof portion 400 a shown in FIG. 13 for example by adhesive applied to interior face 226, or by fasteners, such as screw or nail fasteners, spaced apart along the length of roof bottom plate 255 and driven through the exterior face 227, or by utilizing a combination of adhesive and fasteners.

FIG. 13 additionally depicts a wall end cap 246 positioned along the top edge of wall component 200R. The design of wall end cap 246 was previously described in connection with FIG. 12. The seal plate 223 of wall end cap 246 shown in FIG. 13 has a length and width the same, or substantially the same, as the length and width of the top edge of wall component 200R, so as to cover the entirety, or substantially the entirety, of the top edge of wall component 200R. Wall end cap 246 can be fastened to that top edge for example by adhesive applied to its interior face 226, or by fasteners, such as screw or nail fasteners, spaced apart along the length of wall end cap 246 and driven through its exterior face 227, or by utilizing a combination of adhesive and fasteners.

In FIG. 13, roof bottom plate 255 mates with wall end cap 246. For this purpose, the interlock key 247 of wall end cap 246 is provided with a length the same, or substantially the same, as the length of roof bottom plate 255. That interlock key 247 mates with the interlock slot 228 of roof bottom plate 255 when roof bottom plate 255 and wall end cap 246 are pressed together, with the elongate coupling ridges 248 of wall end cap 246 mating with elongate coupling insets 249 of roof bottom plate 255. Coupling ridges 248 and coupling insets 249 can be the same, or approximately the same, as the lengths of wall end cap 246 and roof bottom plate 255 respectively.

Prior to mating wall end cap 246 and roof bottom plate 255, a compression seal 230 is placed in each of the two seal slots 240 of roof bottom plate 255, with each seal 230 having the same, or approximately the same, length as the slot 240 in which it is inserted. When roof bottom plate 255 and wall end cap 246 are pressed together in a mating relationship, the two compression seals 230 are deformed in the manner described previously to provide four lines of sealing between roof bottom plate 255 and wall end cap 246.

H. Shear Seal (260)

A number of the enclosure component sealing systems described herein and utilized in structure 150 include a shear seal system. An element of that shear seal system is a shear seal 260.

Shear seal 260, which is shown in cross-section in FIG. 16A, is an elongate member having a planar elongate base 231 flanked by two elongate winglets 233. At the intersection of base 231 and each of the winglets 233, there is provided two opposed elongate seal walls 234 (individually referred to as seal walls 234A, 234B), joined to and extending away from base 231 in a diverging relationship at a divergence angle λ where λ<180°, for example λ<90° or in the range of 40°<λ<50°. It is most preferred that λ be the same, or nearly so, as the divergence angle E of the slot walls 244 shown in FIG. 11B. Thus as shown in FIG. 16A, the ends of the seal walls 234 distal from base 231 are further apart than the ends of the seal walls 234 proximate to base 231.

At the end of seal wall 234B distal from base 231, seal wall 234B is joined to an elongate seal closure 237, a planar surface oriented at an upward angle α (relative to the planar orientation of base 231) away from seal wall 234B in a direction toward an elongate seal support 239, described below, with α<90°. A planar cantilevered seal surface 257 is joined to the edge of seal closure 237 that is distal from seal wall 234B, as shown in FIG. 16A.

At the end of seal wall 234A distal from base 231, seal wall 234A is joined to the elongate seal support 239. Proximate to seal wall 234A, seal support 239 comprises an elongate planar region oriented parallel to base 231. Distal from seal wall 234A, seal support 239 comprises an elongate arcuate buttress region. The edge of the arcuate buttress region of seal support 239, which is distal from seal wall 234A, joins cantilevered seal surface 257 proximate to the junction of cantilevered seal surface 257 and seal closure 237 to define a hollow seal chamber 238. Planar cantilevered seal surface 257 is oriented at an upward angle β away from the junction of arcuate buttress 235 and seal closure 237 and terminates at a free end 258, with β<90°, for example β>α.

Shear seal 260 is intended to be received in an elongate seal slot 240, shown for example in FIG. 16B, which has the same geometry as the seal slots 40 utilized to receive compression seals 230. Shear seal 260 is dimensioned to snugly fit within slot 240, such that winglets 233 of seal 260 are received in grooves 242 of slot 240. An exemplary placement of a shear seal 260 is depicted in FIG. 16B, which shows a shear seal 260 placed within the slot 240 of a wall end interlock A 262, described further below. As can be seen, when shear seal 260 is properly positioned in slot 240, both seal wall 234A and seal wall 234B terminate below the level of exterior face 227 of wall end interlock A 262, with seal wall 234A (underlying planar cantilevered seal surface 257) terminating below the level at which seal wall 234B terminates.

Shear seal 260 is preferably utilized where two enclosure components 155 are laterally moved during unfolding, one over the other. In such an instance, the two enclosure components 155 are provided with paired enclosure component sealing structures, with one enclosure component sealing structure mounted on one of the enclosure components 155 (such as on an exterior edge), and the other enclosure component sealing structure mounted on the other of the enclosure component structures 155 (such as on an interior face). Each of the paired enclosure component sealing structures has a shear seal 260, with the two shear seals 260 being oppositely oriented; that is to say, the cantilevered seal surface 257 of each is oriented away from the cantilevered seal surface 257 of the other, and each is oriented in the direction of relative movement. Thus in the case of each of the two shear seals 260, the lateral movement of one enclosure component 155, relative to the other, is in the direction from seal wall 234B toward seal wall 234A. This lateral movement flattens the cantilevered seal surface 257, as well as the seal closure 237, and squeezes down each shear seal 260, such that its seal closure 237 and seal support 239 are urged into seal chamber 238. This permits the opposing planar exterior faces 227 of each of the two enclosure component sealing structures to come into full contact. At the same time, the cantilevered seal surface 257 and seal closure 237 of each shear seal 260 are urged into a generally coplanar relationship, with the planar exterior face 227 of the opposing enclosure component seal structure pressing against them, to create an elongate area of sealing.

Shear seal 260 can be fabricated from a resilient material, such as rubber or plastic, for example polyurethane. Particular embodiments of enclosure component sealing structures utilizing the foregoing compression sealing system are described below.

I. Wall End Interlock A (262), Floor Top Interlock (261) Sealing System

FIG. 17 depicts in exploded form the junction between a floor top interlock 261 and a wall end interlock A 262, each shown in cross-section. The particular junction is shown for illustrative purposes between wall portion 200 s-2 and floor portion 300 b, with floor top interlock 261 positioned along the upper face of floor portion 300 b adjacent first transverse floor edge 120, and with wall end interlock A 262 positioned on the bottom edge of wall portion 200 s-2. In structure 150, wall portion 200 s-2 in FIG. 17 is vertically oriented and floor portion 300 b is horizontally oriented.

In particular, floor top interlock 261 shown in FIG. 17 is a rigid elongate member that has an elongate seal plate 223 with an interior face 226 and an opposing planar exterior face 227. The exterior face 227 preferably is hard and smooth to provide a good sealing surface. Seal plate 223 has a length the same, or substantially the same, as the dimension of floor portion 300 b coinciding with first transverse floor edge 120, so as to cover the top edge of floor portion 300 b proximate to first transverse floor edge 120. Seal plate 223 of floor top interlock 261 has a width the same, or substantially the same, as the width of wall portion 200 s-2. The floor top interlock 261 preferably has a thickness “J” at its interior edge, as shown in FIG. 17, sufficient to accommodate the thickness of any protective layer 218 and/or flooring used to surface floor portion 300 b, such as stone, wood or carpeting.

As shown in FIG. 17, at the exterior edge of the interior face 226 of floor top interlock 261, adjacent first transverse floor edge 120, there is provided a series of elongate stepped locating ridges 254. These stepped locating ridges 254, which have a length the same, or substantially the same, as the length of floor top interlock 261, mesh with the corresponding stepped locating ridges 253. shown on the wall end cap 221 depicted in FIG. 10. Such a wall end cap 221 is located at the exterior edge of wall portion 300 b, as indicated in FIG. 17 by dashed lines.

Still referring to FIG. 17, an elongate seal slot 240 is defined on the exterior face 227 of floor top interlock 261, proximate to the exterior edge of floor portion 300 b (such exterior edge coincides with first transverse floor edge 120). Seal slot 240 has a length the same, or substantially the same, as the length of floor top interlock 261.

Floor top interlock 261 can be secured to the top edge of floor portion 300 b at first transverse floor edge 120 shown in FIG. 17 for example by adhesive applied to interior face 226, or by fasteners, such as screw or nail fasteners, spaced apart along the length of floor top interlock 261 and driven through the exterior face 227, or by utilizing a combination of adhesive and fasteners.

Wall end interlock A 262, also shown in FIG. 17, is a rigid elongate member that has an elongate seal plate 223 with an interior face 226 and an opposing exterior face 227. The exterior face 227 preferably is hard and smooth to provide a good sealing surface. The seal plate 223 of wall end interlock A 262 has a length and width the same, or substantially the same, as the length and width of the bottom edge of wall portion 200 s-2, so as to cover the entirety, or substantially the entirety, of the bottom edge of wall portion 200 s-2, as shown in in FIG. 17.

At the mid-point of the interior face 226 of seal plate 223 of wall end interlock A 262, there is provided an elongate key 222, which has a rectangular cross section and a length the same, or substantially the same, as the length of wall end interlock A 262. Key 222 is received in a corresponding elongate slot formed in the exterior edge reinforcement positioned on the bottom edge of the wall portion 200 s-2 to which wall end interlock A 262 is secured.

Again referring to FIG. 17, an elongate seal slot 240 is defined on the exterior face 227 of wall end interlock A 262, toward the interior edge of wall end interlock A 262 (distal from first transverse floor edge 120). This seal slot 240 has a length the same, or substantially the same, as the length of wall end interlock A 262. Additionally, each of the interior and exterior edges of wall end interlock A 262 define locating slots 229. In the case where the enclosure component 155, in this case wall portion 200 s-2, utilizes the enclosure component laminate design shown in FIG. 7, locating slots 229 receive the edge portions of sheet metal layers 205 and 216, bent down at a ninety degree (90°) angle.

Wall end interlock A 262 can be fastened to the bottom edge of wall portion 200 s-2 for example by adhesive applied to its interior face 226, or by fasteners, such as screw or nail fasteners, spaced apart along the length of wall end interlock A 262 and driven through its exterior face 227, or by utilizing a combination of adhesive and fasteners.

In FIG. 17, floor top interlock 261 mates with wall end interlock A 262. Prior to mating, a shear seal 260 is placed in the seal slot 240 of floor top interlock 261, and a shear seal 260 is placed in the seal slot 240 of wall end interlock A 262. The shear seals 260 placed in the seals slots 240 of floor top interlock 261 and wall end interlock A 262 each has the same, or approximately the same, length as the slot 240 in which it is inserted.

Mating of floor top interlock 261 with wall end interlock A 262 occurs by the bottom edge of wall portion 200 s-2 moving over the top surface of floor portion 300 b, from a folded position to an unfolded position. Thus in the arrangement shown in FIG. 17, such mating will correspond to a movement of wall portion 200 s-2 from the right-hand side of the figure toward the left, with wall end interlock A 262 sliding over floor top interlock 261 until the fully unfolded position is reached. In that fully unfolded position, the shear seal 260 in floor top interlock 261, and particularly its seal surface 257, will be in pressing contact with the exterior face 227 of wall end interlock A 262; and the shear seal 260 in wall end interlock A 262, and particularly its seal surface 257, will be in pressing contact with the exterior face 227 of floor top interlock 261. Consistent with this movement, the shear seal 260 placed in seal slot 240 of floor top interlock 261 is preferably oriented so that the free end 258 of its cantilevered seal surface 257 is directed toward the exterior edge of floor top interlock 261 (toward first transverse floor edge 120), and the shear seal 260 placed in the seal slot 240 of wall end interlock A 262 is preferably oriented so that the free end 258 of its cantilevered seal surface 257 is directed toward the interior edge of wall end interlock A 262 (away from first transverse floor edge 120).

To facilitate mating, it is preferred that planar exterior face 227 of floor top interlock 261 not be parallel to the interior face 226 of floor top interlock 261, or to the top face of wall portion 300 b, but rather be inclined downward, in the direction moving away from first transverse floor edge 120 at an angle γ, as shown in FIG. 17. Likewise, it is preferred that planar exterior face 227 of wall end interlock A 262 be inclined upward, in the direction moving toward first transverse floor edge 120, at the same angle γ, as shown in FIG. 17. Accordingly, when bottom edge of wall portion 200 s-2 moves over the top surface of floor portion 300 b, from a folded position to an unfolded position, the shear seals 260 located in slots 240 of floor top interlock 261 and wall end interlock A 262 will be compressed by the sliding movement of wall end interlock A 262 to provide two elongate sealing areas between floor portion 300 b and wall portion 200 s-2. Also to facilitate mating, there is shown in FIG. 17 a step-down 268 on the exterior face 227 of wall end interlock A 262. Step-down 268 is an abrupt reduction in the thickness of wall end interlock A 262, in the direction moving from the inside edge of wall end interlock A 262 toward the outside edge of wall end interlock A 262, which outside edge in the case of the junction depicted in FIG. 17 is proximate first transverse floor edge 120 when wall portion 200 s-2 is in the fully unfolded position. Step-down 268 is located between the slot 240 and the outside edge of wall end interlock A 262. There is also shown in FIG. 17 a corresponding step-up 269 on the exterior face 227 of floor top interlock 261. Step-up 269 is an abrupt increase in the thickness of floor top interlock 261, in the direction moving from the inside edge of floor top interlock 261 toward the outside edge of floor top interlock 261, which outside edge in the case of the junction depicted in FIG. 17 is proximate first transverse floor edge 120 when floor portion 300 b is in the fully unfolded position. Step-up 269 is located between the slot 240 and the inside edge of floor top interlock 261 (distal from first transverse floor edge 120). Step-down 268 and step-up 269 are appropriately located to act as a “stop” and insure correct alignment of wall end interlock A 262 with floor top interlock 261 as wall end interlock A 262 slides over floor top interlock 261.

J. Wall End Interlock B (263), Wall End Interlock A (262) Sealing System

FIG. 18 depicts in exploded form the junction between a wall end interlock B 263 and a wall end interlock A 262, each shown in cross-section. The particular junction is shown for illustrative purposes between wall portion 200 s-2 and wall component 200P, with wall end interlock B 263 positioned on the interior edge of wall component 200P proximate first transverse edge 108 and wall end interlock A 262 positioned on the vertical edge of wall portion 200 s-2 proximate first longitudinal edge 106. In structure 150, wall portion 200 s-2 depicted in FIG. 18 is vertically oriented and wall component 200P is vertically oriented.

In particular, wall end interlock B 263 in FIG. 18 is an elongate member that has an elongate seal plate 223 with an elongate interior face 226 and an opposing elongate planar exterior face 227. The exterior face 227 preferably is hard and smooth to provide a good sealing surface. Seal plate 223 has a length the same, or substantially the same, as the height of wall component 200P when unfolded, so as to cover the interior edge of wall component 200P proximate to first transverse edge 108. Seal plate 223 of wall end interlock B 263 has a width the same, or substantially the same, as the width of wall portion 200 s-2. In general terms, the design of wall end interlock B 263 is substantially the same as floor top interlock 261 depicted in FIG. 17, except wall end interlock B 263 is thinner because it need not accommodate any flooring; for example, wall end interlock B 263 can have a thickness “I” (not shown in FIG. 18) at its interior edge equal to the thickness of an abutting protective layer 218, such as MgO board.

Still referring to FIG. 18, an elongate seal slot 240 is defined on the exterior face 227 of wall end interlock B 263, proximate the interior edge of wall component 200P positioned adjacent to first longitudinal edge 106. Seal slot 240 has a length the same, or substantially the same, as the length of wall end interlock B 263.

Wall end interlock B 263 can be secured to the interior edge of wall component 200P as shown in FIG. 18 for example by adhesive applied to interior face 226, or by fasteners, such as screw or nail fasteners, spaced apart along the length of wall end interlock B 263 and driven through the exterior face 227, or by utilizing a combination of adhesive and fasteners.

FIG. 18 additionally shows a wall end interlock A 262 positioned along the depicted vertical edge of wall portion 200 s-2. The design of wall end interlock A 262 was previously disclosed in connection with FIG. 17. The seal plate 223 of the wall end interlock A 262 shown in FIG. 18 has a length and width the same, or substantially the same, as the length and width of the depicted vertical edge of wall portion 200 s-2, so as to cover the entirety, or substantially the entirety, of that vertical edge of wall portion 200 s-2, as shown in in FIG. 18. The elongate rectangular key 222 of wall end interlock A 262 shown in FIG. 18 has a length the same, or substantially the same, as the length of that wall end interlock A 262. Key 222 is received in a corresponding elongate slot formed in the exterior edge reinforcement positioned on the vertical edge of the wall portion 200 s-2 to which wall end interlock A 262 is secured. The seal slot 240 of wall end interlock A 262 shown in FIG. 18 has a length the same, or substantially the same, as the length of that wall end interlock A 262. In the case where the enclosure component 155, in this case wall portion 200 s-2, utilizes the enclosure component laminate design shown in FIG. 7, the locating slots 229 of wall end interlock A 262 shown in FIG. 18 receive the edge portions of sheet metal layers 205 and 216, bent down at a ninety degree (90°) angle.

Wall end interlock A 262 can be secured to the vertical edge of wall portion 200 s-2 shown in FIG. 18 for example by adhesive applied to its interior face 226, or by fasteners, such as screw or nail fasteners, spaced apart along the length of wall end interlock A 262 and driven through its exterior face 227, or by utilizing a combination of adhesive and fasteners.

In FIG. 18, wall end interlock A 262 mates with a wall end interlock B 263. Prior to mating, a shear seal 260 is placed in the seal slot 240 of wall end interlock A 262, and a shear seal 260 is placed in the seal slot 240 of wall end interlock B 263. Each of the shear seals 260 placed in the seals slots 240 of wall end interlock A 262 and a wall end interlock B 263 has the same, or approximately the same, length as the slot 240 in which it is inserted.

Mating of wall end interlock A 262 and a wall end interlock B 263 occurs by the vertical edge of wall portion 200 s-2 depicted in FIG. 18 swinging toward and across the interior surface of wall component 200P, as wall portion 200 s-2 moves from a folded position to an unfolded position. Thus in the arrangement shown in FIG. 18, such mating will correspond to a movement of wall portion 200 s-2 from the top of the figure toward the bottom, with wall end interlock A 262 sliding across wall end interlock B 263 until the fully unfolded position is reached. In that fully unfolded position, the shear seal 260 in wall end interlock A 262, and particularly its seal surface 257, will be in pressing contact with the exterior face 227 of wall end interlock B 263; and the shear seal 260 in wall end interlock B 263, and particularly its seal surface 257, will be in pressing contact with the exterior face 227 of wall end interlock A 262. Consistent with this movement, the shear seal 260 placed in seal slot 240 of floor top interlock B 263 is preferably oriented so that the free end 258 of its cantilevered seal surface 257 is directed toward the exterior edge of wall end interlock B 263 (toward first transverse edge 108), and the shear seal 260 placed in the seal slot 240 of wall end interlock A 262 is preferably oriented so that the free end 258 of its cantilevered seal surface 257 is directed toward the interior edge of wall end interlock A 262 (away from first transverse edge 108).

To facilitate mating, it is preferred that planar exterior face 227 of wall end interlock B 263 not be parallel to the interior face 226 of wall end interlock B or to the interior face of wall component 200P, but rather be inclined at an angle γ, as shown in FIG. 17, so that seal plate 223 of wall end interlock B 263 becomes progressively thinner moving away from first transverse edge 108. Likewise, it is preferred that planar exterior face 227 of wall end interlock A 262 be inclined at the same angle γ, as shown in FIG. 17, so that seal plate 223 of wall end interlock A 262 becomes progressively thicker moving away from first transverse edge 108. Accordingly, when vertical edge of wall portion 200 s-2 swings toward and across the interior surface of wall component 200P, from a folded position to an unfolded position, the shear seals 260 located in slots 240 of floor end interlock A 262 and wall end interlock B 263 will be compressed by the sliding movement of wall end interlock A 262 to provide two elongate sealing areas between wall component 200P and wall portion 200 s-2. Also to facilitate mating, as previously described a step-down 268 is provided on the exterior face 227 of wall end interlock A 262. Step-down 268 is an abrupt reduction in the thickness of wall end interlock A 262, in the direction moving from the inside edge of wall end interlock A 262 toward the outside edge of wall end interlock A 262, which outside edge in the case of the junction depicted in FIG. 18 is proximate first transverse edge 108 when wall portion 200 s-2 is in the fully unfolded position. Step-down 268 is positioned between the slot 240 and the outside edge of wall end interlock A 262 (proximate transverse edge 108), as depicted in FIG. 18. Also as depicted in FIG. 18, a corresponding step-up 269 is provided on the exterior face 227 of wall end interlock B 263. Step-up 269 is an abrupt increase in thickness of wall end interlock B 263, in the direction moving from the inside edge of wall end interlock B 263 toward the outside edge of wall end interlock B 263, which outside edge in the case of the junction depicted in FIG. 18 is proximate first transverse edge 108. Step-up 269 is positioned between the slot 240 and the inside edge of wall end interlock B 263 (distal from first transverse edge 108). Step-down 268 and step-up 269 are appropriately located to act as a “stop” and insure correct alignment of wall end interlock A 262 with wall end interlock B 263 as wall end interlock A 262 slides across wall end interlock B 263.

K. Closure Boards

The two closure boards of these inventions, namely perimeter board 310 and roof skirt board 280, are described below.

Perimeter Board (310). The exterior edges of floor component 300, or portions thereof, are optionally provided with a perimeter board 310.

FIG. 19A depicts in cross section an exemplary positioning of perimeter board 310. In particular, perimeter board 310 is designed to be positioned against an I-beam end cap 221, in this instance the I-beam end cap 221 located on an exterior edge of floor portion 300 a. Perimeter board 310 includes an elongate seal plate 223 with an interior face 226 and an opposing exterior face 227. Perimeter board 310 has such length as is desired, such as to span the entirety of the exterior edge of floor portion 300 a. As shown in FIG. 19A, the width of perimeter board 310 can be sufficient to capture the thickness of the floor component 300 a, or floor portion thereof against which it is positioned, plus a portion of the abutting wall component 200 or wall component portion.

The interior face 226 of perimeter board 310 includes an elongate locating key 264, which is rectangular in cross section and dimensioned to be received in accessory slot 224 of I-beam end cap 221. Locating key 264 can be the same length as the perimeter board 310, or can comprise space apart discrete segments. The interior face 226 of perimeter board 310 in FIG. 19A also includes a plurality of elongate clearance slots 266, rectangular in cross section in the embodiment shown, and having a length the same as, or substantially the same as, the length of perimeter board 310. Clearance slots 266 are preferably located so as to be positioned over locating grooves 225 of I-beam end cap 221 when locating key 264 is received in accessory slot 224. When so located, clearance slots 266 provide space for fastener heads driven into locating grooves 225 of I-beam end cap 221 so that perimeter board 310 can be snugly positioned against I-beam end cap 221.

The exterior face 227 of perimeter board 310 depicted in FIG. 19A includes two elongate fastener slots 265, each of which has a dovetail shape in cross section in the embodiment shown, and a length the same as, or substantially the same as, the length of perimeter board 310. A locating groove 225 is provided in each fastener slot 265, so as to facilitate the accurate positioning of nails or other fasteners utilized to secure perimeter board 310 to abutting components.

FIG. 19B depicts in cross section the positioning of I-beam end cap 221, floor top plate 252, wall end cap 246 and perimeter board 310 relative to each other at a junction between wall component 200R and floor portion 300 a. As can be seen, perimeter board 310 masks this junction from external view to achieve a more attractive appearance, as well as providing an additional barrier against the ingress of soil, dust, rain and the like. A resilient strip 267, such as those shown in FIG. 19B, can be snapped into each of the fastener slots 265 to cover any nail or fastener heads exposed in those slots.

Roof Skirt Board. The exterior edges of roof component 400, or portions thereof, are optionally provided with a roof skirt board 280.

FIG. 20 depicts in cross section an exemplary positioning of roof skirt board 280. In particular, roof skirt board 280 is designed to be positioned against an I-beam end cap 221, in this instance the I-beam end cap 221 located on an exterior edge of roof portion 400 a. Roof skirt board 280 includes an elongate seal plate 223 with an interior face 226 and an opposing exterior face 227. Roof skirt board 280 has such length as is desired, such as to span the entirety of the exterior edge of roof portion 400 a. As shown in FIG. 20, the width of roof skirt board 280 can be sufficient to capture the thickness of the roof component 400, or portion thereof against which it is positioned, plus a portion of the abutting wall component 200 or wall portion.

The interior face 226 of roof skirt board 280 includes an elongate cinch key 278, which is preferably serpentine in cross section and dimensioned to be received in accessory slot 224 of I-beam end cap 221. Cinch key 278 can be the same length as the perimeter board 310, or can comprise space apart discrete segments. In turn, the exterior face 227 of roof skirt board 280 includes an elongate fastener slot 265 positioned over cinch key 278. Fastener slot 265 has a dovetail shape in cross section in the embodiment shown, and a length the same as, or substantially the same as, the length of roof skirt board 280. An elongate locating groove 225 is provided in the fastener slot 265 of roof skirt board 280, and provides a visual indication of where to place fasteners during construction.

Roof skirt board 280 facilitates the securing of roofing material, such as thermoplastic polyolefin membrane, to wall components 200. After fully unfolding the roof portions, such roofing material is optionally used to cover the top of roof component 400. The roofing material extending beyond roof component 400 is then folded down to extend between exterior face 227 of I-beam end cap 221 of roof portion 400 a shown in FIG. 20 and interior face 226 of roof skirt board 280. After the roofing material is so positioned, nails or other fasteners are driven at spaced intervals along locating groove 225, to press roof skirt board 280 against the roofing material and secure the roofing material in place between roof skirt board 280 and I-beam end cap 221. Cinch key 278, if provided with a serpentine or like cross section, provides additional area so as to better capture the roofing material. An elongate resilient strip 267, such as the one shown in FIG. 20, can be snapped into fastener slot 265 to cover any nail or fastener heads exposed in this slot.

Enclosure Component Sealing Structure Materials

The enclosure component sealing structures described herein can be fabricated from a number of materials, such as wood, aluminum, plastics and the like. It is preferred to fabricate the enclosure component sealing structures from foamed polyvinyl chloride (PVC), particularly Celuka foamed PVC. This material provides a strong, impact and crack-resistant lightweight material with a hard attractive exterior, which, in addition to contributing a sealing function, additionally contributes to the structural rigidity of the enclosure components 155.

Enclosure Component Sealing Structure Exemplary Placements

The exploded views in FIGS. 8A and 8B of structure 150 depicted in FIG. 1 provide exemplary placements of the enclosure component sealing structures described herein. For illustrative purposes to better understand some of these exemplary placements, certain of the enclosure component sealing structures shown in FIGS. 8A and 8B are shown slightly separated from the enclosure component 155 to which they are fastened.

Referring to FIG. 8A, I-beam end caps 221 can be utilized to seal the horizontal exterior edges of floor portion 300 a (three placements), floor portion 300 b (three placements), roof portion 300 a (three placements), roof portion 300 b (two placements) and roof portion 300 c (three placements). Further, as shown in FIG. 8B and in detail in FIG. 12, the hinged junction between wall portion 200 s-1 and 200 s-2 can be sealed by positioning a wall end cap 246 on the vertical edge of wall portion 200 s-1 and a wall vertical interlock 245 on the vertical edge of wall portion 200 s-2. Likewise, the hinged vertical junction between wall portion 200 s-3 and 200 s-4 can be sealed as shown in FIG. 8B by positioning a wall end cap 246 on the hinged vertical edge of wall portion 200 s-3 and a wall vertical interlock 245 on the hinged vertical edge of wall portion 200 s-4.

In addition, as shown in FIGS. 8A and 8B, and in detail in FIG. 13, the horizontal junction between wall component 200R and roof portion 400 a can be sealed by positioning a roof bottom plate 255 on the bottom face of roof portion 400 a overlying wall component 200R and by positioning a wall end cap 246 on the horizontal edge of wall component 200R, which supports roof portion 400 a. A like seal arrangement can be used to seal the horizontal junctions between roof portions 400 a, 400 b and 400 c, and wall portions 200 s-1 through 200 s-4 (unfolded roof portion 400 b will rest on unfolded wall portion 200 s-2 and also on a section of wall portion 200 s-1, as can be appreciated from FIG. 3), as well as to seal the horizontal junction between roof portion 400 c and wall component 200P. The two vertical exterior edges of wall component 200R can each be sealed by positioning on each of them a wall end cap 246.

In a comparable manner, as shown in FIGS. 8A, 8B and in detail in FIG. 15, the horizontal junction between wall component 200R and floor portion 300 a can be sealed by positioning a wall end cap 246 on the horizontal edge of wall component 200R resting on floor portion 300 a and by positioning on the top face of floor portion 300 a underlying wall component 200R a floor top plate 252. A like seal arrangement can be used to seal the horizontal junctions between floor portion 300 b and wall component 200P, and between floor portion 300 a and wall portions 200 s-1 and 200 s-3, up to the point where wall portion 200 s-1 meets wall portion 200 s-2, and up to the point where wall portion 200 s-3 meets wall portion 200 s-4. The two vertical exterior edges of wall component 200P can be sealed by positioning on each of them a wall end cap 246.

Furthermore, the hinged horizontal junction between roof portion 400 b and roof portion 400 c, as shown in FIG. 8A and in detail in FIG. 14, can be sealed by positioning an I-beam interlock A 250 on interior edge 412 c of roof portion 400 c, and an I-beam interlock B 251 on first interior edge 412 b of roof portion 400 b. Similarly, the hinged horizontal junction between roof portion 400 a and roof portion 400 b shown in FIG. 8A can be sealed by positioning an I-beam interlock A 250 on second interior edge 412 b of roof portion 400 b, and an I-beam interlock B 251 on interior edge 412 a of roof portion 400 a. In like manner, the hinged horizontal junction between floor portion 300 a and floor portion 300 b can be sealed by positioning an I-beam interlock A 250 on the interior edge 301 b of floor portion 300 b and an I-beam interlock B 251 on the interior edge 301 a of floor portion 300 a.

Referring now to FIGS. 8A, 8B and in detail to FIG. 17, the horizontal junction between wall portion 200 s-2 and floor portions 300 a and 300 b can be sealed by positioning a wall end interlock A 262 on the bottom edge of wall portion 200 s-2 and a floor top interlock 261 on the regions of the upper face of floor portions 300 a and 300 b underlying wall portion 200 s-2 when wall portion 200 s-2 is in its fully unfolded position. The horizontal junction between wall portion 200 s-4 and floor portions 300 a and 300 b when wall portion 200 s-4 in its fully unfolded position can be sealed similarly.

Finally, referring to FIG. 8B and in detail to FIG. 18, the vertical junction between wall portion 200 s-2 and wall component 200P can be sealed by positioning a wall end interlock A 262 on the vertical edge of wall portion 200 s-2 that is adjacent to wall component 200P when both wall portion 200 s-2 and wall component 200P are in their fully unfolded positons, and by positioning a wall end interlock B 263 on the region of the interior face of wall component 200P that is adjacent wall portion 200 s-2 when both wall portion 200 s-2 and wall component 200P are in their fully unfolded positions. The vertical junction between wall portion 200 s-4 and wall component 200P can be sealed in like manner.

Enclosure Component Manufacture

For enclosure components 155 having the construction disclosed herein in reference to FIG. 7, the metal sheets 206 and 217 that can be used to form first structural layer 210 and second structural layer 215 respectively can be entirely flat and juxtaposed in a simple abutting relationship. Optionally, metal sheets 206 and 217 can be provided with edge structures that facilitate placement of sheets and panels during manufacture.

Particular edge structure designs for metal sheets 206 and 217 are described in U.S. Nonprovisional patent application Ser. No. 17/504,883 entitled “Sheet/Panel Design for Enclosure Component Manufacture,” having the same inventors as the inventions described herein and filed on Oct. 19, 2021. The contents of U.S. Nonprovisional patent application Ser. No. 17/504,883 entitled “Sheet/Panel Design for Enclosure Component Manufacture,” having the same inventors as the inventions described herein and filed on Oct. 19, 2021, are incorporated by reference as if fully set forth herein, particularly including the exterior and interior edge structure designs described for example at paragraphs 00187-00205 and 00212 and in FIGS. 8, 9A-9C, 23A-23J and 24A-24B thereof.

A facility suitable for manufacturing the enclosure components 155 of the present invention, as well as exemplary manufacturing steps, are also described in U.S. Nonprovisional patent application Ser. No. 17/504,883 entitled “Sheet/Panel Design for Enclosure Component Manufacture,” having the same U.S. Nonprovisional patent application Ser. No. 17/504,883 entitled “Sheet/Panel Design for Enclosure Component Manufacture,” having the same inventors as the inventions described herein and filed on Oct. 19, 2021, are incorporated by reference as if fully set forth herein, particularly including the facility suitable for manufacturing the enclosure components 155 of the present invention, as well as exemplary manufacturing steps, described for example at paragraphs 00178-00186 and 00206-00222, and in FIGS. 22, 23A-23J and 24A-24B.

Enclosure Component Relationships and Assembly for Transport

For ease of transport and maximum design flexibility, it is preferred that there be a specific dimensional relationship among enclosure components 155.

FIG. 2 shows a top schematic view of structure 150 shown in FIG. 1, and includes a geometrical orthogonal grid for clarity of explaining the preferred dimensional relationships among its enclosure components 155. The basic length used for dimensioning is indicated as “E” in FIG. 2; the orthogonal grid overlaid in FIG. 2 is 8E long and 8E wide; notably, the entire structure 150, including perimeter boards 310, preferably is bounded by this 8E by 8E orthogonal grid.

Roof portions 400 a, 400 b and 400 c each can be identically dimensioned in the transverse direction. Alternatively, referring to FIG. 3, roof portion 400 c (which is stacked upon roof portions 400 a and 400 b when roof portions 400 b, 400 c are fully folded) can be dimensioned to be larger than either of roof portion 400 a and roof portion 400 b in the transverse direction for example, by ten to fifteen percent, or by at least the aggregate thickness of roof components 400 a and 400 b. This transverse direction dimensional increase is to reduce the chances of binding during the unfolding of roof portions 400 b, 400 c. In addition, as described in U.S. Nonprovisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” and filed on Feb. 10, 2020, friction-reducing components can be used to facilitate unfolding roof component 400, such as by positioning a first wheel caster at the leading edge of roof portion 400 c proximate to the corner of roof portion 400 c that is supported by wall portion 200 s-2 as roof portion 400 c is deployed, and by positioning a second similar wheel caster at the leading edge of roof portion 400 c proximate to the corner of roof portion 400 c that is supported by wall portion 200 s-4 as roof portion 400 c is deployed. In such a case, roof portion 400 c can be dimensioned larger than either of roof portions 400 a and 400 b in the transverse direction by at least the aggregate thickness of roof components 400 a and 400 b, less the length of the first or second wheel caster.

In FIG. 2, the four wall components 200 are each approximately 8E long, and each of roof portions 400 a and 400 b is approximately 8E long and 2.5E wide. Roof portion 400 c is approximately 8E long and 2.9E wide. In FIGS. 2 and 3, each of floor components 300 a and 300 b is 8H long; whereas floor component 300 a is just over 3E wide and floor component 300 b is just under 5E wide.

The shipping module 100 shown edge-on in FIG. 3 includes a fixed space portion 102 defined by roof component 400 a, floor component 300 a, wall component 200R, wall portion 200 s-1 and wall portion 200 s-3. As shown in FIG. 2, second wall portion 200 s-2 is folded inward and positioned generally against fixed space portion 102, and fourth wall portion 200 s-4 is folded inward and positioned generally against second wall portion 200 s-2 (wall portions 200 s-2 and 200 s-4 are respectively identified in FIG. 2 as portions 200 s-2 f and 200 s-4 f when so folded and positioned). The three roof components 400 a, 400 b and 400 c are shown unfolded in FIG. 1 and shown folded (stacked) in FIG. 3, with roof component 400 b stacked on top of roof component 400 a, and roof component 400 c stacked on top of the roof component 400 b. Wall component 200P, shown in FIGS. 2 and 3, is pivotally secured to floor portion 300 b at the location of axis 105, and is vertically positioned against the outside of wall portions 200 s-2 and 200 s-4. In turn, floor portion 300 b is vertically positioned proximate fixed space portion 102, with wall component 200P pending from floor portion 300 b between floor portion 300 b and wall portions 200 s-2 and 200 s-4.

Sizing the enclosure components 155 of structure 150 according to the dimensional relationships disclosed above yields a compact shipping module 100, as can be seen from the figures. Thus shipping module 100 depicted in FIG. 3, when dimensioned according to the relationships disclosed herein using an “E” dimension (see FIG. 2) of approximately 28.625 inches (72.7 cm), and when its components are stacked and positioned as shown in FIG. 3, has an overall length of approximately 19 feet (5.79 m), an overall width of approximately 8.5 feet (2.59 meters) and an overall height of approximately 12.7 feet (3.87 meters). These overall dimensions are less than a typical shipping container.

It is preferred that the fixed space portion 102 be in a relatively finished state prior to positioning (folding) together of the all other wall, roof and floor portions as described above. In the embodiment shown in FIGS. 1 and 2, wall components 200 are fitted during manufacture and prior to shipment with all necessary door and window assemblies, with the enclosure components 155 being pre-wired, and fixed space portion 102 is fitted during manufacture with all mechanical and other functionality that structure 150 will require, such as kitchens, bathrooms, closets and other interior partitions, storage areas, corridors, etc. Carrying out the foregoing steps prior to shipment permits the builder, in effect, to erect a largely finished structure 150 simply by “unfolding” (deploying) the positioned components of shipping module 100.

Each of the wall, floor and roof components 200, 300 and 400, and/or the portions thereof, can be sheathed in protective film 177 during fabrication and prior to forming the shipping module 100. Alternatively or in addition, the entire shipping module 100 can be sheathed in a protective film. Such protective films can remain in place until after the shipping module 100 is at the construction site, and then removed as required to facilitate enclosure component deployment and finishing.

Shipping Module Transport

The shipping module 100 is shipped to the building site by appropriate transport means. One such transport means is disclosed in U.S. Pat. No. 11,007,921, issued May 18, 2021; the contents of which are incorporated by reference as if fully set forth herein, particularly as found at paragraphs 0020-0035 and in FIGS. 1A-2D thereof. As an alternative transport means, shipping module 100 can be shipped to the building site by means of a conventional truck trailer or a low bed trailer (also referred to as a lowboy trailer), and in the case of over-the-water shipments, by ship.

Structure Deployment and Finishing

At the building site, shipping module 100 is positioned over its desired location, such as over a prepared foundation; for example, a poured concrete slab, a poured concrete or cinder block foundation, sleeper beams or concrete posts or columns. This can be accomplished by using a crane, either to lift shipping module 100 from its transport and move it to the desired location, or by positioning the transport means over the desired location, lifting shipping module 100, then moving the transport means from the desired location, and then lowering shipping module 100 to a rest state at the desired location. Particularly suitable equipment and techniques for facilitating the positioning of a shipping module 100 at the desired location are disclosed in U.S. Nonprovisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” and filed on Feb. 10, 2020. The contents of that U.S. Nonprovisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” and filed on Feb. 10, 2020, are incorporated by reference as if fully set forth herein, particularly including the equipment and techniques described for example at paragraphs 00126-00128 and in connection with FIGS. 11A and 11B thereof.

Following positioning of shipping module 100 at the building site, the appropriate portions of wall, floor and roof components 200, 300 and 400 are “unfolded” (i.e., deployed) to yield structure 150. Unfolding occurs in the following sequence: (1) floor portion 300 b is pivotally rotated about horizontal axis 305 (shown in FIGS. 3 and 4) to an unfolded position, (2) wall component 200P is pivotally rotated about horizontal axis 105 (shown in FIG. 3 behind perimeter board 312) to an unfolded position, (3) wall portions 200 s-2 and 200 s-4 are pivotally rotated about vertical axes 192 and 194 (shown in FIG. 2) respectively to unfolded positions, and (4) roof portions 400 b and 400 c are pivotally rotated about horizontal axes 405 a and 405 b (shown in FIGS. 3 and 4) respectively to unfolded positions.

A mobile crane can be used to assist in the deployment of certain of the enclosure components 155, specifically roof portions 400 b and 400 c, floor portion 300 b, as well as the wall component 200P pivotally secured to floor portion 300 b. Alternatively, particularly suitable equipment and techniques for facilitating the deployment of enclosure components 155 are disclosed in U.S. Nonprovisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” and filed on Feb. 10, 2020. The contents of that U.S. Nonprovisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” and filed on Feb. 10, 2020, are incorporated by reference as if fully set forth herein, particularly including the equipment and techniques described for example at paragraphs 00132-00145 and depicted in FIGS. 12A-14B thereof.

After unfolding, the enclosure components 155 are secured together to finish the structure 150 that is shown in FIG. 1. Perimeter board 312 and roof skirt board 280 provide structures for securing wall, floor and roof components in their deployed positions. If any temporary hinge structures have been utilized, then these temporary hinge structures can be removed if desired and the enclosure components 155 can be secured together. During or after unfolding and securing of the enclosure components 155, any remaining finishing operations are performed, such as addition of roofing material, and making hook-ups to electrical, fresh water and sewer lines to complete structure 150, as relevant here.
